Sienna Miller Just Wore the Fresh Flat-Boot Trend That's All Over H&M and Mango
Wrapping up against the biting British breeze, new mum Sienna Miller was spotted yesterday on a walk in London styling appropriately fuzzy layers. Wearing a Londoner favourite, the actor reached for an oversized shearling coat in a soft oatmeal shade, which she layered over a tonal mushroom-hued jumper for her walk in the city. Tapping into a nostalgic footwear trend that's back on the rise this season, Miller opted for black moto boots from Penelope Chilvers to complete her winter look. Ticking off two trending themes—the flat-shoe trend and the 2010s revival, Miller's footwear choice brought practicality and personality to her casual outfit.
Creating a cohesive colour palette, she styled her beige and brown look with white, straight-leg jeans. Bringing a fresher feel than perhaps a blue pair might have done,
white jeans add a clean touch to any dark outfit, but as evidenced here, look equally chic when styled with lighter tones.
Whilst Miller opted for a casual jeans and boots pairing, we've spotted so many of our favourite influencers take to styling the footwear trend this season. From wool
miniskirts to floaty cotton dresses, moto boots add an edge to outfits that no other boot style can. Winning out hearts for their versatility and solidifying our affection with their comfortable silhouette, moto boots are the winter footwear trend we're backing this season, and Miller is giving us all the styling inspo we need.
